A practical method for the aziridination of α,β-unsaturated carbonyl compounds with a simple carbamate utilizing sodium hypochlorite pentahydrate

The efficient formation oftert-butylN-chloro-N-sodio-carbamate by the reaction of simpletert-butyl carbamate with sodium hypochlorite pentahydrate (NaOCl·5H2O) would be a practical and green method for the aziridination of α,β-unsaturated carbo

Diastereoselective aziridination of chiral electron-deficient olefins with N-chloro-N-sodiocarbamates catalyzed by chiral quaternary ammonium salts

Chiral quaternary ammonium salt-catalyzed diastereoselective aziridination of electron-deficient olefins that possess a chiral auxiliary with N-chloro-N-sodiocarbamates was developed. The key to high stereoselectivity was found to be the employment of the

Preparation of 2,6-Bis(l-menthopyrzol-3-yl)pyridines and their Catalytic Activity for Asymmetric Diels Alder Reaction

3-Aryl-l-menthopyrazoles 1 and 2 and related compounds were prepared from l-menthone, and their enantioselective activities were discussed as chiral ligands. In this series of compounds, 2,6-bis(2-methyl-l-menthopyrazol-3-yl)pyridine (8a), which had both

Diastereoselective α-alkylation of 2-acyl-3-phenyl-l-menthopyrazoles

N-Acylpyrazoles were α-alkylated in good yields by the treatment with alkyl halides after metalation with LDA or LiHMDS. In the case of chiral N-acylpyrazoles, e.g., 2-acyl-3-phenyl-l-menthopyrazoles (4), the α-alkylation was highly diastereoselective. The subsequent α-alkylation products could be converted into esters in good yield in the presence of BF3·OEt2 without the loss of the optical purity.

Stereoselective N-acylation of a new chiral auxiliary compound; 3-phenyl-l-menthopyrazole

As a new chiral auxiliary compound having a pyrazole ring system, the synthetic utility of (4R,7S)-3-phenyl-4-methyl-7-isopropyl-4,5,6,7-tetrahydroindazole (3-phenyl-l-menthopyrazole), which was prepared from l-menthone, was discussed.
